Hi Heidi. Yes both are fine.

Both are correct. The two choices differ grammatically and emphasize different things. Neither is better than the other. "We felt something move" uses a "bare infinitive". In addition to "feel", the verbs "see", "hear", "make", and "let" are often followed by a bare infinitive: "We heard her sing" "They made me dance" "Let me play" "We felt something moving" uses the adjective "moving" to describe "something". In other words we felt something and it was a moving thing. The difference in emphasis comes from the fact that adjectives are descriptive. "Moving" is an adjective that paints a portrait to help you to imagine what was happening. The first choice uses verbs alone. This places the emphasis on action, not description. It doesn't paint a picture. It simply tells what happened.

I would say that ‘felt’ is wrong. ‘Heard’ or ‘saw’ are possible. ‘Move’ and ‘moving’ are both ok, but I think a native speaker would be more likely to use ‘move’ to convey that there was a one-time brief sound. ‘Moving’ would be the more general default.

Both structures are good. You could also use 'saw' instead of 'felt' if you saw the thing move/moving--to feel something move is more typically used when the thing is very close to you/in close proximity, so it's not impossible, but could sound slightly unusual unless you were sitting in the bush and were thus able to 'feel' movement from within it.

Hello Heidi! Both sentences are grammatically correct, but they emphasize different aspects of the experience: Use "move" for a more instantaneous feeling. Use "moving" for a sense of ongoing action. 💡 If you need to practice English everyday, follow me and take the quizzes I share.
